Hey.
Anybody ever get busted for coding during a warranty service visit? i.e. You take it in for service, they somehow magically notice you have frigged with your settings and deny your warranty repair by blaming it on your meddling?

Does anyone de-code their car back to original stock settings before taking it in for warranty service? Just seems like one less thing for them to complain about or blame the failure on.

Decode car is worthless they do have option to verify every change in module , what date and time you read module and make any changes, BUT they usually didnt do that

Eeesh...

I didn't know the ECU logs change date/time. Hm. Bummer.

My guess would be though, if I changed something from "nicht" to "aktiv" then back to "nicht" for example - they would probably only see the last change, no? So they might know I changed it to "nicht" on date/time - but not when I had previously changed it to "aktiv"? I'm just guessing from a purely physical hardware perspective - they can't hold my cruise control speed after power-off but will keep an endless list of module change date/times? No. Actually. That makes sense - CYA first, CUSTOMER second. ha.
